If you were to make a survival horror...

Something akin to Mirrors Edge-like gameplay could make running away pretty cool.

I agree with this guy. There are far too many holdout survival games. I'd make one where there is no way to hold out. You're facing a swarm and the only way to go is OUT. You make it to a checkpoint, you have a moment to grab provisions and maybe a spontaneous weapon. It'd be mostly "run for your life and kill the occasional guy in the way" mixed with quick time events where the floor caves through and you have to get up before you're swarmed or something big breaks through the wall and you've got only split seconds to defend yourself.

Sound like something you all would play?

Consider the idea triple-agreed. There's this one game that did exactly that, but it's old and rare, and I've never played it so I don't know if that style worked well enough to be used again in current-generation consoles. It was called Hellnight (or Dark Messiah in Japan).

Search it on your search engine of choice, I can't post a link it seems.
